<!-- The density here is deliberately depressed so that the thickness
of the mylar volume mocks up the following structure:
1. 6.3 microns of mylar
2. 0.1 microns of aluminum
3. 19.6 microns of air
The air is there to make the layer thick enough for the Geant
tracking code not to miss it due to fp rounding errors. -->
